In a square-foot garden, seeds are planted in squares instead of rows, wasting little space. Using string or bamboo dowels (shown above left), gardeners map out a planting grid in raised beds. Vining
cropsare grown with trellises -- a space saver that also keeps vegetables from rotting on the ground. The benefits of square-foot
gardening? You
can plant the same amount of vegetables in 1/5 of the space, use less water, and no
tilling is required.

The beds can be made any shape you
like, four-by-four, two-by four, six-by-two, etc. Carey has 10 beds and is currently
growing bok choy, herbs, broccoli, peppers, strawberries, onions, tomatoes,
leeks, cabbages, radishes, carrots, Japanese cucumbers and flowers to “confuse
the bugs.”

It’s
not surprising to learn that Carey, 75, would tackle gardening with such aplomb. She also teaches pole
walking, digital photography and computer skills, and is raising her 14-year-old granddaughter. And she recently added square-foot gardening classes at the Los Angeles County Arboretum & Botanic Garden to her busy teaching calendar.

This method is well-suited to seniors, she
says, because the beds can be elevated to eliminate squatting. "Even people in wheelchairs can do it," she says. "Just put it on a sawhorse and
drill holes in the plywood base."

Gardening is a positive way for people to take charge of their lives, she says. "I'm always encouraging people to be more involved in life," she says. "If
there is a God, I want him to tap me on the shoulder when I'm in the middle of
something and tell me it's time to go."
